摘要：

Viscose-based activated carbon fiber supporting silver (ACF(Ag)) was prepared by pretreatment, carbonization, activation, vacuum impregnation and decomposition processes. The ACF(Ag) was characterized by silver content, silver particle size, distribution and antibacterial properties. It was confirmed that the presence of silver decreased the specific surface area of the ACF. The silver content and the surface morphologies of the ACF(Ag) were dependent on initial concentration of AgNO3 solution, immersion time and decomposition temperature, of which AgNO3 content was the most important factor. Factors influencing the resistance to attrition of the ACF(Ag) were also discussed in this paper. The ACF(Ag) containing as low as 0.065 wt% of silver exhibited strong antibacterial property against Escherichia coli and Staphylococcus aureus. (C) 1998 Elsevier Science Ltd. All rights reserved.
